3D Printing Using Genetically Modified Bacteria and Orange Juice

This post is coming to you live from the Elephant & Castle Mini Maker Faire being held today at the London College of Communication.

The JuicyPrint prototype—here the redder light indicates where the cellulose wouldn’t be growing, and the bluer light is where it would. In this case the 3d bio-printer would be printing an ‘H’ symbol.

While the field is still fairly quiet right now, biohacking is the next big thing. There’s a grown segment of the maker movement that is talking about it, but not just that, they’re getting on and doing it.

I talked to Ilya Levantis from the London Biohackspace about JuicyPrint a 3d printer that can be fed with fruit juice and used to print out useful shapes made of bacterial cellulose using a genetically engineered strain of cellulose producing bacteria.

The G. hansenii (Gluconacetobacter hansenii) bacteria that the London Biohackspace is using is a is able to grow on a wide range of things like fruit juice, tea or even brewing waste. Once completed, building objects with the new printer will require only a computer, and a local a trip to your local market for supplies.

The Elephant & Castle Mini Maker Faire was held at the London College of Communication from 10am till 6pm. Entry is free to children (under 16) and students, tickets are £5 otherwise and available on the door.
